Gioia r 02: common questions

What microcontroller does the Gioia r 02 use?

The Gioia r 02 is built around the ATtiny85-20MU, from the AVR/Arduino family.

How big is the Gioia r 02 PCB?

The Gioia r 02 measures 30 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gioia r 02?

59 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gioia r 02 design files?

From the Green-bms/gioia repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Gioia r 02 design in my own project?

The repository has no license, so all rights stay with Green-bms. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gioia r 02 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
